It is fatal in such cases to regard health from a careless or indifferent standpoint. It is a question which must be considered by every one of the legion of working girls and women who labour for their own, and often for others' bread. Looking at it from the most practical standpoint, it will be found to be the greatest economy in the end. If the health is kept at a fair standard of excellence, the mental powers are maintained in a state of useful energy. As soon as health is below par, even when not sufficiently so as to force us to desist from work, the brain loses its elasticity; we are dull, become mere machines instead of intelligent workers, and our duty gets irksome and fails to interest us. And here let us interpose one word. If we wish to spare ourselves that most wearying of all sensations, that fatal sense of boredom and disgust for our daily task which sometimes creeps in upon us, we must try with all our hearts to take an interest in what our hands find to do. "Whatsoever thy hand findeth to do that do with thy might." It is not only right to think and act up to this; it is the greatest wisdom also; for our own comfort and happiness. Work done with a will only takes half the time in doing. The hours fly, and the sense of weariness has no time to creep in. This is a spirit, it will be found, which can be easily cultivated, and will, after a little effort, come quite naturally, much to our benefit in every way. It has seemed to us, in spite of the great advance that has been made in the teaching of hygiene, and the possession by many of a fair knowledge of the laws which govern it, that there is still a lamentable want of practicability in its application; that is to say, the theories we learn, and to which we subscribe, are rarely, and then very imperfectly, carried out in actual individual life. We grant that great improvements are visible on all sides, in what we might term general hygiene; but where we perceive a great deficiency still, is in that personal application of the laws of health which must and can only be properly applied by individuals to themselves, so as to make them fit into the circumstances under which they exist. It will not help our girls much, for instance, to have learnt the number of cubic feet of oxygen that is necessary for turning the purple blood into scarlet--the amount of nitrogenous, phosphatic, carbonaceous, and other elements which are requisite for building up new tissue, etc., etc., and many other dry facts of a kindred nature, if she does not put this knowledge to practical use. There is a wide division between facts thus learnt off glibly at school and the practical application of them to our daily wants.
